(Cincinnati) Duke Energy estimates that up to 4,000 gallons of diesel fuel was released from a tank overfill at the Beckjord Plant. The secondary containment failed to contain the release due to an open valve. The diesel fuel ran straight down the hill and entered the Ohio River. The On Scene Coordinator and U.S. Coast Guard surveyed the river by boat and detected a sheen and diesel odor 1 to 2 miles downstream of the Duke facility. Clean Harbors has deployed 3 boats to search for recoverable product. U.S. Coast Guard reports that Ohio River is closed for 15-mile section (between river miles 453 and 468) and three public water intakes on Ohio River between the Duke Facility and Licking River confluence are shut down.
